Suppose that f and g are functions such that lim f(x) = - 7 x-7- 2 lim g(x) = - 5 Evaluate the following limits. If a limit does not exist, enter "DNE". lim (f (20 ) ) 3 = x- -2 lim 2f(x) + 3g(x) = x-7 -2 f (z) lim = x->-2 gx) lim x- - 2 Vg(z) =63399 if 9:31 Let f :1: = ( ) { 2w 1 if a: > 1 Calculate the following limits. Enter "DNE" if the limit does not exist. r= :1 r= :1 1:21 mo = :1 Next -5 -x +2 if x - 6 Calculate the following limits. Enter "DNE" if the limit does not exist. lim fa = x-6 lim x- - 6+ lim f(x) = x- -6
